Love it, for several reasons:
1. Lots of people who need prepped meals can't access or use programs like Meals on Wheels.
2. I was one such person once, and did indeed pay a neighbour to make me meals. The person stopped almost as soon as they started. I found it impossible to find someone who'd do it reliably. (Like many "tiny gigs", most people won't commit until they have a large customer base.) i.e., In at least my neighbourhood, there was a need and it wasn't yet being met.
3. When FrugalZony mentioned people at Slab City can't get meals outside of certain times, my first thought was similar to the one you had! I'll move to Slab City and sell meals to people out of my RV :)
